Understanding Bcrypt Hashes
A typical Bcrypt hash looks like: $2a$10$N9qo8uLOqpGC123...
Prefix ($2a$)Identifies the algorithm version.
$2a, $2b, and $2y represent secure Blowfish variations.Rounds ($10$)The cost parameter (210 = 1,024 iterations). Higher rounds exponentiate difficulty to protect against GPU-based cracking.
Salt & Hash (53 Chars)The remaining characters contain a cryptographically random 22-character salt followed by the 31-character password hash value.
